eovnnnon' FOR INTERNAL-COMBUSTION ENGINES.

I Application filed November 10, 1924. Serial No. 748,950.

Theobject of my invention is to provide a governor mechanism of simple, durable and inexpensive construction which may be easily and quickly applie'dto an internal combustion engine such as used in automobiles, for.

the purpose of regulating the speed of the engine when the same is being used for power purposes other than advancing the automobile over the ground surface.

My invention consists in the construction, arrangement and combination of the various parts of'the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a top view of my improved governor device the central portion of one of the governor springs being broken away.

Figure 2 is a side elevation of the same showing the manner in which it is applied to an engine.

Figure 3 is an end elevation of my improved device.

Figure 4 is a longitudinal sectional view taken on the line 44 of Figure 2.

Figure 5 is a detail view of the bar which is substituted for the regular locking bar for securing the timer casing in position.

Figure 6 is a detail sectional view taken on the line 66 of Figure 4.

Figure 7 is a plan view of the carburetor, a portion of which is broken away to show the throttle valve and the manner in which it is operated by means of my improved device.

The numeral 10 indicates an engine frame which is provided with the usual cylinder blocks 11 having a timer shaft 19, an intake manifold 12 and a carburetor 13. The forward end of the engine frame is provided with a timer casing 14 surrounding said shaft 19 and formed with a cylindrical portion 15 and a conical portion having an end 16. The cylindrical portion 15 is provided with contact terminals 17 which are mounted in the usual insulation block 18. The timer shaft 19 provides means for operating the movable contact 20, the contact 20 being secured in position by means of a nut applied to the screw threaded portion 2]. of the shaft 19. The nut is removed and a coupling 22 substituted. The end 16 of the casing 14-is provided with an opening 23 through which the coupling 22 extends, so as to form an extension to the shaft 19 and to rotate in unison therewith.

The coupling 22 is provided with a collar 24 having outwardly and forwardly extend ing brackets 25, to each of which is pivoted a bell crank lever 26. One end of each of the levers 26 is provided with a ball 27. The inner ends of the levers 26 are operatively'mounted to a sleeve 28 s'lidably mounted longitudinally on the coupling 22. The forward end of the sleeve 28 is provided with an annular groove 29 designed toreceive the inwardly extending ends 30 of a yoke 31, said yoke being pivotally mounted on one end of a main supporting bracket 32 secured to the front end of the engine frame 10 by means of a bolt 33. The yoke 31 is provided with an outwardly extending arm 34 provided with a spring 35 for yieldably moving the outer end of said arm 34 rearwardly. The said spring 35 has one end mounted to an adjusting screw 36 secured to the bracket 32. The outer end of the lever 34 is provided with a rod 37 which extends to the throttle lever 38 of the carburetor 13. A spring 39 is secured to the balls 27 for the purpose of yieldably "moving them to an inner limit of movement.

Thus it will be seen that when the engine is in operation and the timer shaft 19. is being rotated, the coupling 22 will be rotated, causing the brackets 25 to be rotated and in turn the balls 27. Said balls being moved outwardly from the center of the shaft due to the centrifugal action will cause the sleeve 28 to be moved rearwardly, and the outer end of the lever 34 to be moved forwardly against the action of the spring 35, which will at the same time cause the throttle arm 38* of the carburetor to be moved to a partially closed position, thereby providing means whereby the speed of the engine may be automatically regulated through the regular carburetor control mechanism. The engine may be run at anydesired speed by varying the tension of the spring 35.

It will be seen that the engine will be permitted to pick up its speed until the weight of the balls 27 overcomes the tension of the spring. No throttle action is imparted to the carburetor until such tension has been overcome.

The timer casing 14 is secured in position against the end of the frame 10 by means of a bar 40, provided at one end with prongs 41 to surround the small end of the cone 15. The opposite end of the bar 40 is provided with an openings 42 to receive a bolt 43 from the frame 10.

Thus it Will be seen that I have provided a governor attachment of simple, durable and inexpensive construction, which may be easily and quickly applied to an automobile engine so the same may be used for power purposes.

I claim as my invention:

In combination, a timer shaft having its outer end screw threaded, a timer casing surrounding said shaft, said casing being pro vided with an openin in alinement with said shaft, a coupling for the screw threaded portion of said shaft mounted in alinement therewith and extending through the opening of said casing, a collar for said coupling having outwardly and forwardly projecting brackets a bell crank lever pivotally mounted to each of said bracket-s, each of said levers being provided with a governor ball, a sleeve slidably mounted on the outer end of said coupling member and operatively connected with the inner ends of said bell crank levers, a supporting bracket, a yoke in operative relation with said. sleeve and pivotally mounted on said supporting bracket having an outwardly extending arm, springs for connecting the balls of said governor, an auxiliary spring having one end connected to said yoke and its opposite end adjustably connected to said support, and link devices for operatively connecting the free end of said yoke with the throttle valve of a carburetor.
